PS# 6. Barra Gaelic and Secondary Articulations (due Oct. 25)
In the original feature geometry proposed by Halle (1982), the secondary articulation features of
palatalization and velarization are a function of the longue body features [·back] and (+ back],
which are terminal features of the Dorsal articulator. The astrisk is used to indicate that the
major articulator, which implements the structure feature of (continuant] as well as the root
node [consonantal). Thus, plain vs. palatalized /sl are represented as below.

Examine the following paradigm of data from Barra Gaelic on next page. In this language there
is a contrast between plain and palatalized consonants. There is also a process inserting an
epenthetic vowel in a sonorant·obstruent consonant cluster. The problem concerns the features

preceding context. What node in the feature tree is the site of spreading? What problems arise in
trying to mai ntain the feature geometry above? Do the data bear on the question of radical vs.
contrastive underspecification? Palatalized consonants are marked by C' in the data source. Also
